Question

An air conditioning system is designed to condition the cold winter air (coming from outside) to the comfort zone as shown in the attached psychrometric chart. According to the available climate data, the temperature of this air varies between 3 °C and 12 °C and its relative humidity also varies within 20% and 60%. Due to the shortage of water (in the area that the air conditioning system is used) to be supplied to this air condition system (if needed) it is preferred to operate the system in a way that its water consumption is as low as possible (even zero if possible). Which of the following components do you suggest to be used to build this air conditioning system such that the system would not fail to serve the purpose at any possible inlet air temperature and relative humidity (within the range suggested by the climate data)?

Explanation / Answer

The comfort of human requires humdity to be between 30-60% and specially in winter it is advised to keep it above 30%.The humidity below this will cause discomfort and various respiratory problems.In this case the humidity will fall below 30% if a humidifier is not used so A heating coil with a steam humidifier must be used here.
